What Stately does
Stately is a developer-tools SaaS company headquartered in Orlando, Florida, founded in 2021 by David Khourshid, the creator of the open-source XState JavaScript/TypeScript library for state machines, statecharts, and the actor model. The company operates with a small team of approximately nine named members (David, Gavin, Farzad, Mateusz, Jenny, Laura, Anders, Nick, and Kevin) and serves JavaScript/TypeScript developers and engineering teams who need to model, simulate, and deploy complex application logic across frontend user flows, backend workflows, and business processes. Visible customers include AWS, Netflix, Microsoft, Lyft, Epic Games, Cisco, T-Mobile, Stitch, Coder, Thoughtworks, and Domestic Data Streamers, indicating usage across media, telecommunications, financial technology, cloud, gaming, and IT consulting.
The core product surface is Stately Studio, a visual software modeling platform featuring a drag-and-drop editor with Design and Simulate modes, bidirectional code-to-diagram synchronization, automatic test path generation, and a Stately Inspector that visualizes live actors and inter-actor communication as sequence diagrams. The Studio is built on top of the open-source XState library, with framework integration packages (@xstate/react, @xstate/vue, @xstate/svelte), the @xstate/store state management library, and utility packages (@xstate/graph, @xstate/test). A VS Code extension, Figma Sync, and GitHub Sync extend the platform into IDE, design, and code-hosting environments. Optional Stately AI features (powered by OpenAI) generate flows from natural language, produce diagram summaries, and scaffold React apps from diagrams. Infrastructure dependencies include Vercel (hosting), Supabase (database), Stripe (billing), Partykit (real-time collaboration), Algolia (search), and Sentry (error tracking).
The business model is freemium SaaS with four tiers: a free Community plan, a Pro plan for individual developers, a Team plan for shared projects, and an Enterprise plan with Data Processing Agreement (DPA) support and custom contracts on multi-year terms. Distribution is product-led through self-serve signup, npm-distributed XState packages, the VS Code Marketplace, and a community-led marketing mix (public Discord, GitHub feedback board, YouTube Office Hours, blog, and social channels), with a Calendly-assisted sales overlay for larger prospects. The company has raised $2,000,000 in a single funding round in May 2021 (investors undisclosed) and has not publicly disclosed revenue.

Stately product offering
Product offeringCore offering
Stately builds Stately Studio, a visual software modeling platform for designing, simulating, and deploying application and business logic as state machines, statecharts, and actors. The platform pairs a drag-and-drop editor with bidirectional code-to-diagram synchronization, automatic test generation, and AI-assisted flow creation. It is built on top of XState, Stately's open-source JavaScript/TypeScript library for state management and event-driven logic orchestration.
Product overview
Stately offers a unified platform-plus-modules architecture centered on Stately Studio, a visual software modeling platform built around the open-source XState library for orchestrating application logic via state machines, statecharts, and the actor model. The core XState JavaScript/TypeScript library is the foundation, while Stately Studio provides the drag-and-drop Editor (Design and Simulate modes), collaboration via Projects and Teams, the Stately Inspector for debugging running apps, and a VS Code extension. Optional AI capabilities (Stately AI, powered by OpenAI) extend the Studio with generative flow creation, diagram summaries, and the experimental "Generate React app" feature. The ecosystem is rounded out by official framework integration packages (@xstate/react, @xstate/vue, @xstate/svelte), the @xstate/store state management library, and utility packages (@xstate/graph, @xstate/test).

Stately competitors and assessment
Company assessmentBroad incumbents
- Lucidchart: Lucidchart is a broad visual diagramming incumbent used for flowcharts, UML, and state diagrams. It overlaps with Stately on the visual authoring of logic diagrams but lacks XState's executable runtime and developer-tool integration.
- Miro: Miro is a broad collaborative whiteboard with flowcharting and diagramming capabilities. It competes with Stately Studio on collaborative visual design but is not a runtime state management platform.
- diagrams.net (draw.io):
Direct peers
- Mermaid: Mermaid is a diagrams-as-code library popular with developers for rendering state diagrams and flowcharts from text. It competes head-on with Stately on state-diagram visualization and is widely embedded in developer documentation tools.
- Structurizr: Structurizr offers the C4 model and a DSL plus visual tooling for software architecture diagrams. It targets the same "diagram-driven software modeling" niche as Stately, with an emphasis on architecture rather than runtime statecharts.
Others
- Redux: Redux is the most widely deployed JS/TS state-management library. It is the incumbent Stately must displace in frontend codebases; Stately explicitly supports auto-visualizing Redux code to ease that migration.
- Zustand: Zustand is a lightweight JS state management library comparable to Stately's @xstate/store package. It represents a competing simple-state default that could reduce demand for the full Stately visual studio.
